The power window was first introduced by Packard in 1940, followed by Ford Motor Company in 1941. Over time this popular convenience accessory has become standard equipment on many cars and light trucks. Improvements in drive systems that are quieter and more efficient as well as "One Touch" window control systems have led to a more complex power window system and the need for strong electrical/electronic diagnostic skills to accurately diagnose and repair power windows.Today's power window systems are controlled and monitored by the vehicle's on-board computer system.
Years ago the basic power window system consisted of an electric motor that drives a scissors type regulator and was controlled by a simple switch. Diagnosis of this system was easy... Check for power at the switch, check for power coming out of the switch when it was activated, and check for power at the motor. Simply put, start at the power source and test for power at each component until you found the component that didn't work properly. Today's power window systems are much more involved and complicated to work on.
Common causes of Power Window failures are:
Faulty motor- Window won't operate at all.
Faulty switch/control circuit assembly- One or more windows operate intermittently or only in one direction.
Broken Regulator Assembly- Window Comes Off Track or Shifts as window is operated. May not operate at all on some systems and an audible noise from the motor can be heard.
Faulty Body Control Module/Computer- May operate erratically and a diagnostic trouble code may be stored in the computer.
